A liquid mixture of 20 mol benzene 50 mol toluene and 30, Ask an Expert

Academics

Find the lowest temperature of vaporization and the highest temperature when there is liquid left over.

A liquid mixture of 20 mol% benzene, 50 mol% toluene and 30 mol% xylene is to be partially vaporized at 1 atm pressure. You are asked to find out the range of temperatures which could be used for this process.

	Antoine constants: pressure [=] mmHg Temperature [=] C			at 1 atm (degreesC)
	A	B	C
Benzene	6.89	1203	220	80.1
Toluene	6.96	1347	220	110.6
Xylene	7.00	1467	214	140

1. What is the lowest temperature at which vaporization could occur? ___________ Degrees C.
(provide answer to within +/- 5 °C)

2. What is the highest temperature that could be used and liquid still be present? __________ Degrees C.
(provide answer to within +/- 5 °C)
